Compare the telephone network & internet. List few similarities & differences.

1. A telephone network is a connection oriented circuit switched network. This means that a connection must be established between the two endpoints. Bandwidth is reserved for this circuit.

The Internet is a connectionless packet switched network. This means that packets can be sent without following an established connection and bandwidth can be shared with other users.

2. In a telephone network, there is a dedicated connection established between the two end users and it is a fixed line also the it has got a fixed monthly rental for the connection but call charges are extra based on the duration of the call and region(local or STD).

In case of Internet there is no dedicated connection but the all authorized users are connected to the network using a unique IP and the cost will be dependent on the data downloads being made. 

3. Telephone network can only give one to one connection only using a dedicated channel in the network.

Internet can have one-to-many connections through any channel which is free at that point of time.

4. In case of Telephone networks the billing is done based on the duration of the call and area of calling.

In case of internet the billing will be mainly on the usage of the data in bits per second.

5. The telephone network will be able to connect to internet network using a dial up connection and a dial up modem, but the data rate will be very low.

But in case of internet the connection is made to the network using a broadband modem and hence the data rate will be very high.
